need some long distance help, evil sound coming from rt rear Options

[double-a]

this car has been absolutely trouble-free since we bought it, but today it's got me worried.

for a few weeks, the right rear side of the car has exhibited an occasional "wiggle," usually at freeway speeds. at first i thought it wasn't balanced, but the guys a scwhab do a good job, and it's only an occasional wobble, like it's bouncing up and down. shakes the car real good too.

now, as of yesterday, there's a weird squeak or squeal from the right rear. it's only audible at very slow speeds, such as slowing to a stop, turning into the driveway, etc. it doesn't sound like brake squeal, it's much more evil sounding. but definitely coming from the tire/wheel area.

so what's going on here? bushings, bearings? i'm not real technically savvy, but i can take the wheel off and take a look in there, if someone wants to give me an idea of what to look for.

ok, yanked the wheel off. i don't know where the bushings are, so i can't check their condition. but the wheel, when off the ground, does not move in and out. no movement at all, but i did notice something odd. the caliper is clamped down on the rotor. the hub turns ok, but is encountering a lot of resistance. looks like the caliper is out of adjustment or something. e-brake is disengaged.
